Abstract: ENERGY CONSERVATION SYSTEM PROVIDING CURRENT CONTROL     Abstract of the Disclosure An electrical energy conservation control method and apparatus are provided which produce  efficient regulation light output of either incandescent or fluorescent lamps or the outputs of other electrical load devices under cir-cumstances where full output is not required.  The control method and apparatus combines electronic (transistor) switch-ing techniques with the use of reactive circuit components to provide control of the r.m.s. level of current flowing through the load device during the AC input voltage sine wave and to permit some current flow at all times during each voltage half wave.  The control technique is non-dissipative in the sense that losses are virtually limited to switching transitions and passive circuit element losses.  The control is accomplished by controlling the time period that a tran-sistor is saturated full-on.  The transistor is saturated on at the beginning of each voltage half wave and continues to be saturated on until the point in time within each half wave when the transistor is turned off.  At that point in time, a non-dissipative current-limiting capacitor provides an alter-nate current path for the load current.

Abstract: TRANSDUCER ALIGNMENT METHOD FOR WEIGHT AND               BALANCE SYSTEM                Abstract of the Disclosure A method of determining the alignment of a first transducer mounting surface relative to a second transducer mountng surface includes utilizing a laser in conjunction with first and second precision ground fixtures secured to the first and second transducer mounting surfaces, respectively.  An optically flat mirror is carried by each of the fixtures, with the mirror of the first fixture being partially light-transmissive.  The incident light beam from the laser is directed at the partially light-transmissive mirror which, in turn, reflects part of the incident beam to form a first reflected beam.  The remaining portion of the incident beam is transmitted and is reflected by the other mirror to form a second reflected beam.  The two beams reflected by the mirrors are projected upon a screen disposed in front of the laser, such screen having an aperture through which the incident beam passes.  The position of the laser and screen is adjusted so that the reflected beam from one of the mirrors falls at a predetermined location on the screen.  The horizontal and vertical distances on the screen of the reflected beams from the incident beam are measured and are used in an equation to determine the angular alignment of the transducer mounting sur-faces relative to one another.

Abstract: Abstract of the Disclsoure A cabinet push lock has a key plug held by a retaining pin engaged in a circumferential groove in the key plug and mounted in a bore coplanar with the pin tumbler bores.  The pin tumbler stacks are held in their bores by an elongated cap mounted in a groove closed at the front and extending across both the pin tumbler bores and the retaining pin bore.  The cap is held against endwise movement, as by interlocking with the sides of the groove.  The groove side walls are staked at spaced areas to releasably retain the cap, and other areas are reserved for subsequent restakings.          The retaining pin bore, an aligned diametric bore in the key plug, and a bottom opening in the lock body provide a passage for transmission of thrust to drive a portion of the cap out of the groove to permit cap removal.  The diametric bore in the key plug contains a drive pin to block the key slot, and a key stop ahead of the drive pin blocks an additional portion of the key slot.  Cap-removing thrust is exerted by driving the drive pin against the retaining pin and thereby driving the retaining pin against the overlying portion of the cap.         A capping tool is provided to control the swaging so as to permit repeated recappings and hence easy and repeated recombinatings of the lock.

Abstract: ABSTRACT A microprocessor or other digital logic circuit recurrently tests the logical switching state of an input port.  Based upon the outcome of such testing, the logical switching state at an output port is switched to the state opposite that of the input port.  The recurrent testing develops at the output port a rectangular wave voltage that switches between upper and lower voltage levels.  A filter coupled between the two ports develops at the input port a voltage representative of the average value of the output port voltage.  The recurrent testing of the logical switching state of the input port produces a negative feedback of the output port voltage to the input pork.          The negative feedback develops a pulse-width modulated voltage at the output port that has an average value that is a multiple of the logic threshold voltage level of the digital logic circuit.  To enable the digital logic circuit to perform a comparison of an analog voltage with a DC reference voltage, a second, comparison input port is coupled to the output port and is biased by the output port voltage at the logic threshold voltage level.  The analog voltage and the DC reference voltage are then applied to the comparison input port.  When the analog voltage exceeds the reference voltage, the voltage at the comparison port exceeds the logic threshold voltage level, resulting in the port being in a first logical switching state, and when the analog voltage is below the reference voltage, the voltage at the comparison port is below the logic threshold voltage level resulting in the input port being in the other logical switching state.

Abstract: ABSTRACT OF THE DISCLOSURE     An aerial towed battle target having a mechanism for radar detection and comprising a hollow body which is reinforced in the front in a ring-like manner and is composed of sewn together woven lengths of fabric into which are integrated elongated metal elements.  The hollow body has a base and towing gear associated with the front.  The problem with heretofore known targets is locating and taking bearings with shortwave radio beams during approach and take-off when the direction of flight coincides extensively with the beam direction.  To improve the inventive target in this respect, the elongated metal elements are contained in the fabric lengths as weft threads which are disposed essentially trans-verse to the direction of towing.  These metal weft threads are incorporated between the woven weft threads, with the spacing between the metal threads increasing over the length of a woven fabric pattern uniformly from a relatively small dimension to a relatively large dimension.  With regard to the increase of the spacing between the picked or shot-in metal elements, the fabric lengths are alternately reversed.
